Plumed Basilisk
Basiliscus plumifrons

The Plumed Basilisk, also called the Green Basilisk, is a water-loving lizard. As the alternative name indicates,
it is basically green. It is native to Central America. The name Basilisk is from a mythical reptile with a mitre
or crown on its head, whose look can turn one to stone.

Basilisks are also called Jesus Christ Lizards since they (all species of Basilisk) can run upright over water using their long tails for balance/float.

The male, above right, has a crest on his head, back and tail. The female (above left) has only a small lump on the head.
They can moderate their colour a little to blend with the background.
